The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199).

For example, first content (for example, object 901, 902 in FIG. 9 ) may be displayed in a first display area in the reduced state, and first content (for example, object 901, 902 in FIG. 9 ) and second content (for example, marking 903 related to audio data in FIG. 9 ) may be separately displayed in a first display area and in a second display area, respectively, in the expanded state. According to an embodiment, the microphone 207 may acquire audio. For example, the microphone 207 may acquire audio corresponding to the user's voice. The electronic device 101 may acquire audio data corresponding to audio acquired through the microphone 207. For example, the electronic device 101 may acquire audio data corresponding to the user's voice acquired through the microphone 207. According to an embodiment, the number of microphones 207 included in the electronic device 101 may not be limited. For example, the electronic device 101 may include multiple microphones 207.

According to an embodiment, the electronic device 101 may, among the multiple microphones 207, distinguish and acquire audio data according to the position in which corresponding multiple microphones 207 are included (disposed) in the electronic device 101. For example, multiple microphones 207 may be disposed at the upper and lower ends of the electronic device 101, data acquired through a first microphone disposed at the upper end may be distinguished and stored as first audio data (for example, external audio data), and data acquired through a second microphone disposed at the lower end may be distinguished and stored as second audio data (for example, user audio data).

According to an embodiment, the electronic device 101 may use the touch display 205 so as to display an image (or icon) distinguished so as to correspond to audio data acquired through the first microphone and the second microphone. For example, the electronic device 101 may store data including audio data and a handwriting input, and may display at least one object (for example, object 901, 902 in FIG. 9 ) corresponding to the stored data. The electronic device 101 may mark an object 901 including multiple pieces of audio data acquired through multiple microphones, among the at least one object 901, 902, so as to be distinguished from the other object 902. For example, the electronic device 101 may provide different markings (for example, microphone markings) so as to distinguish first audio data (for example, external audio data) over second audio data (for example, user audio data). In addition, the electronic device 101 may change, based on a user input regarding each distinguished marking (for example, microphone marking), an area including an object related to audio data (for example, first audio data, second audio data) (for example, operation 403 in FIG. 4 ). For example, when second audio data among first audio data and second audio data is deactivated (for example, not played back) based on a user input, the electronic device 101 may deactivate (for example, change transparency of) an area including an object mapped in relation to the second audio data. For example, the electronic device 101 may distinguish and display the visual effect and/or attribute (for example, thickness, color, or saturation of text) of an object mapped in relation to first audio data and an object mapped in relation to second audio data.

According to an embodiment, the memory 209 may store various pieces of data used by components of the electronic device 101 (for example, processor 201, speaker 203, touch display 205, and microphone 207) temporarily or non-temporarily. For example, the memory 209 may store data corresponding to a touch input acquired through the touch display 205.

FIG. 3 is a flowchart 300 of operations in which an electronic device 101 according to an embodiment displays an object mapped to an audio playback point-in-time through a first screen.

A series of operations described below may be performed simultaneously by the electronic device 101 or performed in a changed order, and some operations may be omitted or added.

In operation 301, the electronic device 101 may execute a first application. The first application may be a handwriting software application (or note application), and is not limited to the terminology. For another example, the first application may be understood as a software application including a function for playing audio corresponding to audio data and displaying an object associated with the audio. For still another example, the first application may be understood as a software application including a function for displaying, while audio is played, an object associated with a playback point-in-time of the audio. The object may include at least one of a text, a stroke, an image, a text box, or a web card.

According to an embodiment, the electronic device 101 may acquire a user input for executing the first application. In response to acquisition of the user input, the electronic device 101 may execute the first application. The user input may include at least one of a button input, a touch input, a gesture input, a drag input, or a voice input. For example, the electronic device 101 may acquire the user's touch input for executing the first application through the touch display 205. In response to the acquired touch input from the user, the electronic device 101 may execute the first application. The user input is not limited to the above-mentioned examples, and may include various input methods for executing the first application.

In operation 303, in response to execution of the first application, the electronic device 101 may display a first screen corresponding to the first application. For example, the electronic device 101 may display a first screen including an area for inputting a handwriting, in response to execution of a handwriting application. For example, the UI of the first screen may be referred to FIG. 9 . According to an embodiment, in response to execution of the first application, the electronic device 101 may enter an operation mode for the first application. After entering the mode for the first application, the electronic device 101 may display a preview screen (for example, UI 900 in FIG. 9 ) including at least one content (for example, object 901, 902 in FIG. 9 ) corresponding to a data file (for example, memo file) of the first application. The at least one content may include a thumbnail-type image that displays at least a part of the content. The at least one content may include a visual object (for example, marking 903 related to audio data in FIG. 9 ) according to characteristics of the content. For example, content (for example, object 901 in FIG. 9 ) including both handwriting data and audio data may include a visual object (for example, marking 903 related to audio data in FIG. 9 ) indicating audio. In response to acquisition of an input for selecting the at least one content, the electronic device 101 may display a screen (for example, first screen) corresponding to the at least one content. In operation 305, the electronic device 101 may acquire a first input for playing audio data of the first application. The electronic device 101 may acquire a first input for playing audio data stored through the first application. For example, the electronic device 101 may acquire a first input for playing audio data related to a class stored through a handwriting application.

According to an embodiment, the electronic device 101 may acquire a first input for playing content of the first application. Data of the content may include at least one of audio data or handwriting data. The audio data and the handwriting data may be associated based on time information. For example, a playback point-in-time at which audio corresponding to the audio is played and a handwriting corresponding to the handwriting data may be mapped.

In operation 307, in response to acquisition of the first input for playing audio data of the first application, the electronic device 101 may output audio corresponding to the audio data through the speaker 203. For example, in response to acquisition of a user input for playing content of the handwriting application, the electronic device 101 may output audio corresponding to audio data related to a class through the speaker 203.

In operation 309, the electronic device 101 may determine whether an object mapped to the playback point-in-time of the audio is displayed in the first screen currently displayed on the display. According to an embodiment, the electronic device 101 may identify whether an object associated with the audio exists. When the object exists, the electronic device 101 may determine the position of the identified object. Based on the position of the identified object, the electronic device 101 may determine whether the object is displayed in the first screen. The first screen may be the entire area or partial area (for example, area in which text is displayed) of the current screen displayed in response to execution of the first application. For example, the electronic device 101 may identify whether a handwriting mapped to a playback point-in-time (for example, a point-in-time of three minutes that lapses from the starting time of the audio) of the audio exists. When the handwriting exists, the electronic device 101 may determine the position of the identified handwriting. Based on the determined position, the electronic device 101 may determine whether the handwriting displayed in the first screen.

According to an embodiment, the electronic device 101 may display an object mapped to a playback point-in-time of the audio on the first screen or may display the object after changing the attribute (for example, thickness, color, or saturation of text) of the object. For example, the electronic device 101 may change the color of the text mapped to a playback point-in-time of the audio from a vague color to a dark color and then display the color text. According to an embodiment, when the object is displayed in the first screen, the electronic device 101 may perform operation 311 and, when the object is not displayed in the first screen, the electronic device 101 may perform operation 313.

In operation 311, when an object mapped to a playback point-in-time of the audio is displayed in the first screen, the electronic device 101 may omit auto scroll regarding the object. For example, when audio related to a class is being output, and if a handwriting mapped to a playback point-in-time of the audio is displayed in the first screen, the electronic device 101 may omit auto scroll regarding the handwriting and may maintain the first screen.

In operation 313, the electronic device 101 may perform auto scroll such that the first screen is changed to a second screen including an identified object. The first screen and the second screen may be understood as screens displayed in response to selection of an object corresponding to identical data (for example, identical document file) stored in the first application. The first screen and the second screen may be at least partially overlap or may not overlap. In the process of changing from the first screen to the second screen through the auto scroll, the first screen may be moved while being automatically scrolled upwards or downwards. The auto scroll may be understood as a function for performing scroll automatically such that the screen displayed by the electronic device 101 is changed. For example, when an object mapped to an audio playback point-in-time is not displayed on the first screen, the electronic device 101 may change the position of the area displayed on the touch display 205 to a second screen including the object, through auto scroll. For example, when a screen including an object mapped to an audio playback point-in-time is positioned below the screen currently displayed on the display, the electronic device 101 may move the screen currently displayed on the display upwards through auto scroll such that the screen including the object is displayed through the touch display 205 by such conversion. As another example, when a screen including an object mapped to an audio playback point-in-time is positioned above the screen currently displayed on the display, the electronic device 101 may move the screen currently displayed on the display downwards through auto scroll such that the screen including the object is displayed through the touch display 205 by such conversion.

FIG. 4 is a flowchart 400 of operations in which an electronic device 101 according to an embodiment determines whether or not to perform auto scroll, based on an area including an object.

A series of operations described below may be performed simultaneously by the electronic device 101 or performed in a changed order, and some operations may be omitted or added.

Referring to FIG. 4 , the electronic device 101 may determine an area including an object mapped to a playback point-in-time of an outputted audio. The electronic device 101 may determine whether or not to perform auto scroll, based on whether the determined area is displayed on a first screen.

In operation 401, the electronic device 101 may identify whether an object mapped to an audio playback point-in-time exists. According to an embodiment, when the identified object exists, the electronic device 101 may perform operation 403 and, when the identified object does not exist, the electronic device 101 may perform operation 307.

In operation 403, when an object mapped to the audio playback point-in-time exists, the electronic device 101 may determine an area including the object mapped to the audio playback point-in-time. The electronic device 101 may determine at least one of the position of the determined object or the position of the determined area. For example, the electronic device 101 may configure a rectangular area including the determined area and may determine the center of the rectangular area as the position of the rectangular area. The position of the area is not limited to the center of the area, and may be determined to be any point in the area. The electronic device 101 may acquire the x-coordinate and y-coordinate of the area, and may determine the position of the area, based on the acquired coordinates. The electronic device 101 may determine, based on the determined area position, whether the determined area is positioned above or below the first screen. The area may refer to an area surrounding the object. For example, the area may be a quadrangular area surrounding the object. The shape is not limited to the above-mentioned examples.

In operation 405, based on the determined area position, the electronic device 101 may determine whether the area including the object mapped to the audio playback point-in-time is included in the first screen. When the x-coordinate and y-coordinate of the determined area are included in the coordinate range of the first screen, the electronic device 101 may determine that the determined area is included in the first screen. The coordinate range may be configured with reference to coordinate (0, 0) of the left lower end of the first screen. For example, when the coordinate of the determined area is (3, 5), and when the coordinate range of the first screen is (0, 0) to (50, 70), the electronic device 101 may determine that the determined area is included in the first screen. The coordinate range is not limited to the above-mentioned examples. For another example, the coordinate range may be configured with reference to coordinate (0, 0) of the left upper end of the first screen. For still another example, when the coordinate of the determined area is (−3, −5), and when the coordinate range of the first screen is (0, 0) to (−50, −70), the electronic device 101 may determine that the determined area is included in the first screen.

According to an embodiment, when the determined area is included in the first screen, the electronic device 101 may perform operation 407 and, when the determined area is not included in the first screen, the electronic device 101 may perform operation 409.

In operation 407, when determined area is included in the first screen, the electronic device 101 may omit performing auto scroll and maintain the first screen.

In operation 409, when the determined area is not included in the first screen, the electronic device 101 may perform auto scroll such that the screen currently displayed on the display is changed from the first screen to a second screen including the determined area. For example, when the determined area is positioned above the first screen, the electronic device 101 may move the first screen downwards through auto scroll such that the screen currently displayed on the display is changed from the first screen to a second screen including the determined area. As another example, when the determined area is below above the first screen, the electronic device 101 may move the first screen upwards through auto scroll such that the screen currently displayed on the display is changed from the first screen to a second screen including the determined area. For example, it may be determined whether the determined area is positioned above or below the first screen in view of the y-coordinate of the determined area and the coordinate range of the first screen. The first screen and the second screen may be understood as screens displayed in response to selection of an object corresponding to identical data (for example, identical document file) stored in the first application. According to an embodiment, when a second area including a second object mapped to a second audio playback point-in-time is positioned below a first area including a first object mapped to a first audio playback point-in-time, the electronic device 101 may move the first screen including the first area upwards through auto scroll such that the same changes to the second screen including the second area. As another example, when a second area including a second object mapped to a second audio playback point-in-time is positioned above a first area including a first object mapped to a first audio playback point-in-time, the electronic device 101 may move the first screen including the first area downwards through auto scroll such that the same changes to the second screen including the second area. The second playback point-in-time may be understood as a point-in-time after a time lapse from the first playback point-in-time.

FIG. 5 is a flowchart 500 of operations in which an electronic device 101 according to an embodiment minimizes screen movements through auto scroll.

A series of operations described below may be performed simultaneously by the electronic device 101 or performed in a changed order, and some operations may be omitted or added.

In operation 501, the electronic device 101 may display a first object mapped to a first audio playback point-in-time in a first screen. The operation of displaying the first object in the first screen may be performed after operation 311 or 313 in FIG. 3 is performed. For example, the first object may be displayed in the first screen by performing auto scroll or without performing the auto scroll.

In operation 503, the electronic device 101 may determine whether a second object mapped to a second audio playback point-in-time is displayed in the first screen. According to an embodiment, when the second object is displayed in the first screen, the electronic device 101 may perform operation 505 and, when the second object is not displayed in the first screen, the electronic device 101 may perform operation 507.

In operation 505, when the second object is displayed in the first screen, the electronic device 101 may omit performing auto scroll such that the first screen keeps displaying the second object. The electronic device 101 may omit performing the auto scroll and may maintain the first screen.

In operation 507, when the second object is not displayed in the first screen, the electronic device 101 may determine whether the first and second objects can be displayed in a single screen. For example, when the distance between the position of a first object mapped to a first playback point-in-time of audio and the position of a second object mapped to a second playback point-in-time of the audio is less than the size of the first screen, the first and second objects may be displayed in a single screen.

According to an embodiment, when multiple objects including first and second objects can be displayed in a first screen, the electronic device 101 may display the first object in the first screen around an object (for example, second object) related to a playback point-in-time (for example, second playback point-in-time) after a time lapse. For example, the electronic device 101 may display the second object at the center of the first screen and may display the first object at the upper end of the first screen.

According to an embodiment, when the first and second objects can be displayed in a single screen, the electronic device 101 may perform operation 509 and, when the first and second objects cannot be displayed in a single screen, the electronic device 101 may perform operation 511.

In operation 509, when the first and second objects can be displayed in a single screen, the electronic device 101 may perform auto scroll such that the first screen is changed to a second screen including the first and second objects. When the first and second objects can be displayed in a single screen, the electronic device 101 may change the first screen to the second screen including the first and second objects by performing the auto scroll.

In operation 511, when the first and second objects cannot be displayed in a single screen, the electronic device 101 may perform auto scroll such that the first screen is changed to a third screen including the second object, not the first object. Operation 511 in FIG. 5 may correspond to operation 313 in FIG. 3 and operation 409 in FIG. 4 .

FIG. 6 is a flowchart 600 of operations in which an electronic device 101 according to an embodiment generates playback data.

A series of operations described below may be performed simultaneously by the electronic device 101 or performed in a changed order, and some operations may be omitted or added.

In operation 601, the electronic device 101 may execute a first application. The first application may be understood as a handwriting application, and is not limited to the terminology. For another example, the first application may be understood as an application including a function for playing audio corresponding to audio data and displaying an object associated with the audio. Operation 601 in FIG. 6 may correspond to operation 301 in FIG. 3 .

In operation 603, the electronic device 101 may display a first screen corresponding to the first application. Operation 603 in FIG. 6 may correspond to operation 303 in FIG. 3 .

In operation 605, the electronic device 101 may acquire audio data corresponding to audio acquired through the microphone 207. While displaying the first screen, the electronic device 101 may acquire an event that starts an audio input. The event may include an input for selecting an object displayed on the first screen. In response to acquisition of the event, the electronic device 101 may acquire audio through the microphone 207. For example, in response to acquisition of the event, the electronic device 101 may acquire audio generated during a lecture through the microphone 207.

In operation 607, the electronic device 101 may acquire object data (e.g., text data) corresponding to an object mapped to an input point-in-time of the acquired audio. While the electronic device 101 acquires audio through the microphone 207, the electronic device 101 may acquire a handwriting input through the touch display 205. The acquired audio and the acquired handwriting input may be associated in relation to an input point-in-time of the acquired audio. For example, while the electronic device 101 acquires audio through the microphone 207, the electronic device 101 may acquire an object mapped to an input point-in-time (for example, a point-in-time of three minutes that lapses from the starting time of the audio) of the acquired audio through the touch display 205. The electronic device 101 may acquire object data corresponding to the acquired object.

In operation 609, the electronic device 101 may identify an event that ends acquisition of the audio and object (e.g., text). The ending event may include an input for selecting an object displayed on the first screen. In response to acquisition of an input for selecting an object displayed on the first screen, the electronic device 101 may sense an event that ends acquisition of the audio and object.

In operation 611, the electronic device 101 may generate playback data including audio data and object data mapped to an input point-in-time of the audio data.

In response to identifying an event that ends acquisition of audio and object inputs (operation 609 in FIG. 6 ), the electronic device 101 may generate first playback data including audio data and object data mapped to an input point-in-time of audio data. The electronic device 101 may store the generated first playback data. Operation 701 in FIG. 7 may correspond to operation 611 in FIG. 6 .

In operation 703, the electronic device 101 may generate second playback data. The operation of generating the second playback data may be substantially identical to the operation of generating the first playback data. The first playback data may be understood as first audio and handwriting data stored in a first handwriting file of a handwriting application, and the second playback data may be understood as second audio and handwriting data stored in the first handwriting file of the first application. FIG. 7 illustrates two pieces of playback data generating operations, but is not limited thereto, and multiple pieces of playback data including third playback data may be generated.

In operation 705, the electronic device 101 may acquire a user input for synthesizing playback data. For example, when multiple pieces of playback data are stored in the first handwriting file of the handwriting application, a user input for synthesizing the multiple pieces of playback data may be acquired.

In operation 707, in response to acquiring the user input for synthesizing playback data, the electronic device 101 may synthesize first playback data and second playback data. Synthesis of pieces of playback data may refer to converting multiple pieces of playback data into a single piece of playback data. According to an embodiment, when first playback data, second playback data, and third playback data are stored in the first handwriting file of the first application, the electronic device 101 may synthesize the first playback data, the second playback data, and the third playback data.

The object 1005 related to audio playback may indicate a second playback point-in-time 1001-2 (for example, a point-in-time of 6 minutes 37 seconds that lapses from the starting time of the audio) of the audio. While the audio is outputted, the electronic device 101 may determine whether a text 1021-2 mapped to the second playback point-in-time 1001-2 of the outputted audio is displayed on the first screen 801. When the text 1021-2 is not displayed on the first screen 801, the electronic device 101 may convert the screen through auto scroll such that the text 1021-2 is displayed on the first screen 801. For example, the first screen 801 illustrated in FIG. 10B does not display the second text 1021-2 mapped to the second playback point-in-time 1001-2 of the audio, and the electronic device 101 may thus convert the screen to the first screen 801 illustrated in FIG. 10C by using auto scroll such that the second text 1021-2 mapped to the second playback point-in-time 1001-2 of the audio is displayed on the first screen 801.

FIG. 10D illustrates the first screen 801 displayed after audio data is played. The object 1005 related to audio playback may indicate a third playback point-in-time 1001-3 (for example, a point-in-time of 40 minutes 12 seconds that lapses from the starting time of the audio) of the audio. While the audio is outputted, the electronic device 101 may determine whether a text 1021-3 mapped to the third playback point-in-time 1001-3 of the outputted audio is displayed on the first screen 801. When the text 1021-3 is not displayed on the first screen, the electronic device 101 may convert the screen through auto scroll such that the text 1021-3 is displayed on the first screen 801. For example, the first screen 801 illustrated in FIG. 10C does not display the third text 1021-3 mapped to the third playback point-in-time 1001-3 of the audio, and the electronic device 101 may thus convert the screen to the first screen 801 illustrated in FIG. 10D by using auto scroll such that the third text 1021-3 mapped to the third playback point-in-time 1001-3 of the audio is displayed on the first screen 801 at the third playback point-in-time 1001-3.

According to an embodiment, the electronic device 101 may determine whether an image displayed in the first screen 801 is associated with an object (for example, text). When content (for example, image and text) of the first application is generated and stored, association between the content (for example, image and text) may be together determined and stored. When the image and the object are associated, the electronic device 101 may fix the image in an area in the first screen 801 and may perform auto scroll with regard to the object, thereby converting the first screen 801. When the image and the object are not associated, the electronic device 101 may perform auto scroll with regard to the image and the object, thereby converting the first screen 801.
